Some physical investigations on Ag2S thin films prepared by sequential thermal evaporation

Kinetic investigation of silver sulfide phase transformations

“…Determined high values of activation energies (Table 2) indicate to temperature as main factor of influence in confirmed processes of Ag 2 S phase transition, which are in agreement with literature [8,9,19].…”

[Ag{S2CNR(C2H4OH)}] as Single‐Source Precursor for Ag2S – Synthesis, Decomposition Mechanism, and Deposition Studies

“…[1] In addition, bulk α-Ag 2 S shows good photoelectric and thermoelectric properties, which allow to use this material in diverse optical and electronic devices, such as IR detectors, photoconductors, [2] photosensitive materials for recording media, [3] solar-selective coatings, [4] ion-selective electrode membranes, [5] gas sensors, [6] and solid state memory devices. [7,8] For the preparation of silver sulfide thin films, several synthetic methodologies including chemical bath deposition, [9] spray pyrolysis, [1,10] thermal evaporation, [3,11,12] molecular beam epitaxy, [13] sol-gel processes, [14] sulfurization, [15] successive ionic-layer adsorption and reaction, [16] electrodeposition, [17] electroless deposition, [18] electrochemical ion-exchange processes, [19] direct conversion, dip-coat-1 GC-MS, and NMR experiments. Because of the better solubility of 3b, this complex was tested for Ag 2 S spin-coating deposition studies on different substrates (SiO 2 /Si, TiN/SiO 2 / Si, glass) with subsequent annealing at 450°C under a N 2 atmosphere.…”

“…[9][10][11][12][13][14][15][16][17][18][19] Besides this classical synthesis approach, which has some drawbacks, [6] the single-source-precursor approach, in which the precursor molecules contain all the elements that are required for the formation of the target material, shows some advantages. These are, for example, excellent layer uniformity, composition, and phase control, low cost, scalability, [6] and facile development of metallic nanoparticles in organic-inorganic hybrid matrices.…”

Characterization of Electrodeposited Cadmium Selenide Thin Films

“…It is noted that there are some oxygen, carbon and other contamination of the films that can be attributed to contamination of the surface, grain boundaries etc. of the film from the atmosphere 9 . Structural properties X-ray diffraction studies were carried out on both substrate and the CdSe films in order to identify the bulk structure and the different phases present.…”
